Synthesis and mesogenic properties of a Y-shaped glyco-glycero-lipid

Thermotropic and lyotropic liquid crystalline phases of Guerbet branched-chain -D-glucosides

“…maltoside with C 20 and C 24 ), a more complex polymorphism was observed, with an L α -Q -H II phase sequence [31,37]. Thermotropic polymorphism in amphitropic compounds such as glycolipids is rather uncommon, but has been previously observed in certain systems [38], and there are other branchedchain glycolipids whose behaviour has been extensively studied [38][39][40][41][42][43]. Some common trends have been found, such as the formation of inverse nonlamellar phases for the monosaccharide (glucose and galactose) lipids [38,44].…”

Structures of micelles formed by synthetic alkyl glycosides with unsaturated alkyl chains

“…Again, we have observed a possible lyotropic cholesteric phase. The ability to form strong hydrogen bonding networks is typical for amidic functions in glycolipids [21]. Table 1 Lyotropic phase sequence of the synthesized compounds in the contact preparation with water…”

Synthesis of the Fatty Esters of Solketal and Glycerol-Formal: Biobased Specialty Chemicals

“…Specifically, 1- O -dodecylpropanetriol was shown to have a smectic phase in the temperature interval 32–48 °C, very similar to the intervals observed in our case for 3 and 4 . Additional support for the liquid crystal behavior came also by the evidence that analogous glycol-glycerol-lipid compounds also showed comparable mesogenic properties [37]. Unlike 3 and 4 , upon heating, the C 12 fatty acid derivative (2,2-dimethyl-1,3-dioxolan-4-yl)methyl dodecanoate ( 2 ) showed only one broad transition around its melting point between 40 and 48 °C (Figure S8).…”
